f6 Claims. (01. 14u-ss).

This invention relates. to a method of" making barbed wire structures.Barbed wire is' -used as obstacles against the passage of men or beasts.At present a large amount of barbed wire is used in. making barbwire-entanglements to prevent the passage of foot troops. The standardwire used is the common two-wire type No. 12 A. S.

8: W. gage with four-point barbs spaced approximately 4 inches apart.This wire is shipped to the front on reels weighing 50 to 100 poundswhere the barbed wire entanglements are con- Figs. 2 and 3.

as th 'desired spacing of the barbs, is-provided.

The cross wires are cut on a bias as. shown at In in Fig. 1 and the cutwires are bent to form a substantially V-shaped barb 12. Each cross wireis bent in a direction opposite to that of the wires adjacent thereto asclearly shown in In making a barbed wiremat, such as sh'own in Fig. 4,substantially thesame method is followed, Party of the longitudinal;wires l4 are cut on a bias and bent into barbs I8 which exstructed froma multiple of barbed wire strands which in most instances are arrangedin parallel rows. If one or two of th'e'botto'niwires are cut, the enemycan pass through th entanglement.

It is an object of this invention to provide a barbed wire which is muchlighter in weight than the present standard barbed wire,

Another object is to provide a barbed'wire mat which may beused in placeof a plurality of strands of barbed wire. I

A further object is to provide a novel method of making barbed wirestructures.

These and other objects will be more apparent after referring to thefollowing specification and attached drawings, in which: I

Fig. 1 shows a welded wire fabric from which the barbed wire is made;

Fig. 2 shows the completed barbed wire of the present invention;

Fig. 3 is an end view of the barbed wire. of s- Fig. 4 is a view of thebarbed wir mat of the present invention;

Fig. 5 shows one form of barb used in the present invention;

Figs. 6 and 7 disclose modifications ofthe barb; Figs. 8 and 9 show theuse of the mat in building obstacle fences; I

Figs, 10 to 13, inclusive, show-various modifications and adaptations ofthe barbed wire mat.

Referring more particularly to the drawings, the reference numeral 2indicates'a welded wire fabric from which the barbed wire structure-ofthe present invention can be made. The welded wire-fabric 2 consists ofa plurality of'longitu-- tend from the mat in one direction. 7 Thecompleted mat consists of a plurality of longitudinal wires l4 and aplurality of cross wires or pickets It to which barbs I8 are fastened.This mat may be used in fields and roads to puncture pneumatic tires ofenemy planes or'land vehicles.

The barbs may assume various shapes. As shown in 'Fig'. 5, the barb isbent on a sharp radius around the cross wire Hi. The barb 22 of Fig.6 isbentaround the wire l8 ona larger radius and extends upwardly at asharper angle than the barb 28. The barb 24-of Fig. 7 has a flat portion26 and extends upwardly at substantially the same angle as barb 22.

A welded wire fabric 2, of the desired weight having the spacing of thecross wires the same Fig. 8 shows how the mats are utilized to make adouble apron fence. A mat 28 with the barbs facing upwardly is laidagainst one side of a standard fence post 38 and a second mat 28 is laidagainst the post 38 from the other side.

The bottoms of the mats 28 are anchored by means of pegs 32.

Fig. 9 discloses the use of the mats inamoat I In making a moat fenceU-type line posts I at an angle of about 45. Both mats have their barbsextending toward the enemy.

Fi 10 shows a mat 36 used as an overhang on a fence 38. This mat differsfrom the previ-' 'ous mat in having the barbs welded to the iongitudinal strands. Fig. 11 is similar to Fig. 10, but discloses a mat 28having the barbs welded to the cross wires.

Fig. 12 discloses a special type of mat 42 which has two lines of barbs4t fastened to the top of the cross wires or pickets 46. This particulartype oi. mat is used as a fence and the two lines of barbs u preventcattle from leaning against the top strands of the fence.

Fig. 13 discloses a mat 48 which may be used as a fence or as part of atrap. The top strand is cut and bent downwardly to form the barbs 80which discourage climbing or any form of top wire loading.

While various modifications of the invention have been shown anddescribed, it will be appar-i ent that other modifications may be madewithout departing from the scope of the attached claims.

I claim:

1. The method of making a barbed wire struc-- ture which comprisesproviding a welded fabric having a plurality of wires extending in onedi- 1 rection welded to a plurality of wires extendin transversely ofsaid first wires, severing at least one of said transverse wires betweensaid first named wires, and bending the cut wires into substantiallyV-shaped barbs.

2. The method of making single strand barbed wire which comprisesproviding a welded fabric having a plurality of wires extending in one(11- rection welded to a plurality 01 wires extending transversely'ofsaid first wires, the spacing of transversely of said first wires, thespacing of the transverse wires being the same as the desired spacing ofthe barbs, cutting the transverse wires on a bias between the firstnamed wires, and

bending the transverse wires into substantially.

V-shaped barbs.

4. The method of making single strand barbed wire which comprisesproviding a welded fabric having a plurality of wires extending in onedirection welded to a plurality-'Qof wires extending transversely ofsaid first wires;- the spacing of the transverse lwires being the sameas the desired spacing of the barbs, severing the transverse wiresbetween the first named wires, and bending the transverse wires intosubstantially V-shaped barbs, each transverse wire being bent in adirection opposite to the wire adjacent thereto.

5. The method of making a barbed wire mat which comprises providing awelded fabric having a plurality of wires extending in one directionwelded to a plurality of wires extending transversely of said firstwires, severing p rt of said transverse wires between said first namedwires, and bending the cut wires into substantially V-shaped barbs.

6. The method of making a barbed wire mat 1 which comprises providing awelded fabric havmg a plurality of wires extending in one directionwelded to a plurality of wires extending transversely of said firstwires, cutting part of said transverse wires on a bias between saidfirst named wires, and bending the cut wires into substantially V-shapedbarbs extending in one direction from the surface of the mat.
